FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard CISPR 15 has been prepared by CISPR subcommittee F: Interference
relating to household appliances, tools, lighting equipment and similar apparatus.
This consolidated version of CISPR 15 consists of the seventh edition (2005) [documents

1 Domaine d’application
La présente norme concerne l'émission (rayonnée et conduite) des perturbations radio-
électriques:
– de tous les appareils d'éclairage dont la fonction principale est de produire et/ou de
distribuer la lumière, qui sont prévus à des fins d'éclairement lumineux et destinés à être
raccordés au réseau d'alimentation électrique à basse tension ou à fonctionner sur piles;
– de la partie des appareils à fonctions multiples destinée à l'éclairage lorsqu'une des
principales fonctions de ces appareils est l'éclairement lumineux;
– des appareils auxiliaires indépendants exclusivement destinés à être utilisés avec les
appareils d'éclairage;
– des appareils à rayonnement ultraviolet et infrarouge;
– des enseignes publicitaires au néon;
– des appareils d'éclairage public/éclairage d'ambiance uniquement destinés à l'utilisation
extérieure;
– des appareils d'éclairage des moyens de transport (installés dans les bus et les trains).
Les appareils suivants sont exclus du domaine d'application de la présente norme:
– les dispositifs d’éclairage fonctionnant dans les bandes de fréquences ISM (telles que
définies dans la résolution 63 (1979) du Règlement des radiocommunications de l’UIT);
– les dispositifs d'éclairage pour avions et pour aéroports;
– les appareils pour lesquels les exigences relatives à la compatibilité électromagnétique
dans la gamme des radiofréquences sont formulées de manière explicite dans d'autres
normes CEI ou CISPR.
NOTE Des exemples sont donnés ci-dessous:
– les dispositifs d'éclairage intégrés à d'autres appareils, par exemple l'éclairage d'une échelle graduée ou les
indicateurs au néon;
– les photocopieurs;
– les projecteurs de diapositives;
– les dispositifs d'éclairage pour les véhicules routiers.
La bande des fréquences couvertes s'étend de 9 kHz à 400 GHz.

and/or other standards shall meet the provisions of each clause/standard with the relevant
functions in operation.
The limits in this standard have been determined on a probabilistic basis to keep the
suppression of disturbances within economically reasonable limits while still achieving an
adequate level of radio protection and electromagnetic compatibility. In exceptional cases,
additional provisions may be required.

LIMITS AND METHODS OF MEASUREMENT OF
RADIO DISTURBANCE CHARACTERISTICS OF ELECTRICAL LIGHTING
AND SIMILAR EQUIPMENT
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

LIMITS AND METHODS OF MEASUREMENT OF
RADIO DISTURBANCE CHARACTERISTICS OF ELECTRICAL LIGHTING
AND SIMILAR EQUIPMENT
1 Scope
This standard applies to the emission (radiated and conducted) of radiofrequency disturbances
from:
– all lighting equipment with a primary function of generating and/or distributing light intended
for illumination purposes, and intended either for connection to the low voltage electricity
supply or for battery operation;
– the lighting part of multi-function equipment where one of the primary functions of this is
illumination;
– independent auxiliaries exclusively for use with lighting equipment;
– UV and IR radiation equipment;
– neon advertising signs;
– street/flood lighting intended for outdoor use;
– transport lighting (installed in buses and trains).
Excluded from the scope of this standard are:
– lighting equipment operating in the ISM frequency bands (as defined in Resolution 63
(1979) of the ITU Radio Regulation);
– lighting equipment for aircraft and airports;
– apparatus for which the electromagnetic compatibility requirements in the radio-frequency
range are explicitly formulated in other IEC or CISPR standards.
NOTE Examples are:
– built-in lighting devices in other equipment, for example scale illumination or neon devices;
– photocopiers;
– slide projectors;
– lighting equipment for road vehicles.
The frequency range covered is 9 kHz to 400 GHz.
Multi-function equipment which is subjected simultaneously to different clauses of this standard
and/or other standards shall meet the provisions of each clause/standard with the relevant
functions in operation.
The limits in this standard have been determined on a probabilistic basis to keep the
suppression of disturbances within economically reasonable limits while still achieving an
adequate level of radio protection and electromagnetic compatibility. In exceptional cases,
additional provisions may be required.

3 Terms and definitions
For the purposes of this document, the terms and definitions contained in IEC 60050(161)
apply.
Continuous disturbance may be either broadband, for instance caused by the switching
operations or by unstable gas-discharges in the lamp electrode region, or may be narrowband,
for instance caused by electronic control devices operating at dedicated frequencies.
NOTE Instead of the concept of "broadband" and "narrowband", a distinction is made in this standard between two
related kinds of disturbance, defined by the type of the applied detector. For this purpose, limits have been defined
with respect to the measurement with the quasi-peak detector and with the average detector. By using this
approach, a combination of broadband and narrowband disturbances can also be assessed.

4 Limits
4.1 Frequency ranges
In 4.2, 4.3 and 4.4, limits are given as a function of frequency range. No measurements need
to be performed at frequencies where no limits are specified.
NOTE The World Administrative Radiocommunications Conference (WARC) has in 1979 reduced the lower
frequency limit in region 1 to 148,5 kHz; for applications falling within the scope of this standard, tests at 150 kHz
are considered adequate, since 148,5 kHz falls within the receiver bandwidth.
4.2 Insertion loss
The minimum values of the insertion loss for the frequency range 150 kHz to 1 605 kHz are
given in Table 1.

NOTE 2 The voltage disturbance limits are derived for use with an impedance stabilization network (ISN) which
presents a common mode (asymmetric mode) impedance of 150 Ω to the control terminal.

4.4 Radiated electromagnetic disturbances
4.4.1 Frequency range 9 kHz to 30 MHz
The quasi-peak limits of the magnetic component of the radiated disturbance field strength in
the frequency range 9 kHz to 30 MHz, measured as a current in 2 m, 3 m or 4 m loop antennas
around the lighting equipment, are given in Table 3a.
The limits for the 2 m loop diameter apply to equipment not exceeding a length of 1,6 m,
those for the 3 m loop diameter for equipment having a length in between 1,6 m and 2,6 m and
those for the 4 m loop diameter for equipment having a length in between 2,6 m and 3,6 m.

The quasi-peak limits of the electric component of the radiated disturbance field strength in the
frequency range 30 MHz to 300 MHz, measured in accordance with the method specified in
Clause 10 of CISPR 22, are given in Table 3b.
NOTE For reasons of repeatability is it advised to terminate the mains supply cable with a CDN positioned on the
ground plane and terminated with a 50 Ω impedance.

Tests in the frequency range 30 MHz to 300 MHz may be conducted by the test specified in
Annex B with the limits of Table B.1. If the lighting equipment complies with the requirements
of Annex B, it is deemed to comply with the limits of this subclause.
5 Application of the limits
5.1 General
Applications of the limits for the various kinds of lighting equipment as mentioned in the scope
of this standard are given in 5.2 to 5.10.
No emission requirements apply to lamps other than self-ballasted lamps nor to auxiliaries
incorporated in luminaires, in self-ballasted lamps or in semi-luminaires. (See, however, note 2
of 5.3.1 in this respect.)
– 12 – CISPR 15 © IEC:2005+A1:2006+A2:2008
The disturbance caused by manual or automatic operation of a switch (external or included in
equipment) to connect or disconnect the mains shall be disregarded. This includes manual
on/off switches or, for example, switches activated by sensors or ripple control receivers.
However, switches which will be repeatedly operated (e.g. such as those of advertising signs)
are not included in this exception.
5.2 Indoor luminaires
5.2.1 General
The following conditions apply to all kinds of indoor luminaires irrespective of the environment
in which they are used.
5.2.2 Incandescent lamp luminaires
Incandescent lamp luminaires where the lamps are a.c. mains or d.c. operated, or which do not
incorporate a light regulating device or electronic switch, are not expected to produce
electromagnetic disturbances. Therefore, they are deemed to fulfil all relevant requirements of
this standard without further testing.
NOTE Where, in this standard, the term "incandescent lamp" is used, all types of incandescent lamps including
halogen lamps are meant.
5.2.3 Fluorescent lamp luminaires
The minimum values of insertion loss of Table 1 shall apply where a fluorescent lamp luminaire
is a starter switch operated type and designed for one of the following lamp types:
– linear fluorescent lamps with a nominal diameter of 15 mm, 25 mm or 38 mm;
– circular fluorescent lamps with a nominal diameter of 28 mm or 32 mm;
– U-type fluorescent lamps with a nominal diameter of 15 mm, 25 mm or 38 mm;
– single-capped fluorescent lamps, without integrated starter and with a nominal diameter of
15 mm;
– single-capped fluorescent lamps, linear shaped, twin and quad tube, with integrated starter
and having a nominal tube diameter of 12 mm.

5.3 Independent auxiliaries exclusively for use with lighting equipment
5.3.1 General
Independent auxiliaries are electric or electronic devices designed to be applied external to a
luminaire and to be used to control the current or voltage of a discharge or incandescent lamp.
Examples are dimmers, transformers and convertors for lamps, ballasts for discharge lamps
(including fluorescent lamps) and semi-luminaires for compact fluorescent lamps and for
incandescent lamps.
NOTE 1 The requirements described in this subclause (5.3) are for the sole purpose of checking the
electromagnetic emission characteristics of the auxiliary itself. Due to the variety of wiring circuits, it is impossible
to describe requirements for the installation. In this respect, it is recommended that the manufacturer give
guidelines for the proper use of the auxiliary.
NOTE 2 The requirements of this subclause (5.3) may be used for testing auxiliaries intended to be built into a
luminaire. However, there is no obligation for such testing. Moreover, even when the auxiliary complies with the
requirements of this subclause, the luminaire will always be tested.
5.3.2 Independent light regulating devices
5.3.2.1 Types of devices
There are two types of light regulating devices: those like dimmers which directly regulate the
lamps, and those which have a remote control function to regulate the light output via a ballast
or convertor.
5.3.2.2 Independent directly operating light regulating devices
Where such devices incorporate semiconductors, they shall comply with the terminal voltage
limits given in Tables 2a and 2b, otherwise no limits apply.
When several light regulating devices are contained in one product or enclosure, and when
each individual device consists of an entirely self-contained regulating circuit (including all
suppression components) and operates independently of the others (i.e. does not control,
either by design or fortuitously, any load controlled by another individual regulator), then each
device is tested separately.
5.3.2.3 Independent remote control devices
Where such devices generate a d.c. or low-frequency (<500 Hz) control signal, no limits apply.
For radiofrequency or infrared operating devices, this standard does not apply. Other
independent remote control devices shall comply with the requirements of 4.3.1 and 4.3.3.
5.3.3 Independent transformers and convertors for incandescent lamps
5.3.3.1 General
Transformers for incandescent lamps change only the voltage and do not convert the mains
frequency, whereas convertors also convert the frequency. Both kinds of devices can
incorporate means for regulating the light output of the lamps.

5.3.3.2 Independent transformers
For voltage transformers for incandescent lamps which do not regulate the voltage by means of
active electronic components, the condition of 5.2.2 applies. Other independent transformers
for incandescent lamps shall comply with the terminal voltage limits given in Tables 2a and 2b.
5.3.3.3 Independent convertors
Independent electronic convertors for incandescent lamps shall either:
a) comply with the terminal voltage limits given in Tables 2a and 2b; or,
b) where the convertor has a non-detachable load supply cable, or where the manufacturer
gives strict installation instructions which define the position, type and maximum length of
cable(s) to be connected to the lamp(s), then the convertor shall comply with the terminal
voltage limits given in Table 2a and with the radiated disturbance limits given in Tables 3a
and 3b, under these conditions.
5.3.4 Independent ballasts for fluorescent and other discharge lamps
5.3.4.1 Independent ballasts designed for a type of fluorescent lamp as mentioned in 5.2.3
and operated with starter shall comply with the minimum values of insertion loss given in
Table 1.
5.3.4.2 Other independent ballasts shall comply with the mains terminal voltage limits given in
Table 2a.
Where the ballast supplies the lamp with a current having a frequency in excess of 100 Hz, it
shall comply with the radiated disturbance limits given in Tables 3a and 3b.
Where the light is regulated by an external device with separate control lines, the disturbance
voltage at the control terminals shall comply with the requirements of 4.3.3.
5.3.5 Semi-luminaires
Semi-luminaires for compact fluorescent lamps and for incandescent lamps, sometimes called
adaptors, are devices equipped, on the one side, with an Edison screw or bayonet cap to allow
mounting in a standard incandescent lampholder and, on the other side, with a lampholder to
allow the insertion of a replaceable light source.
Semi-luminaires shall comply with the terminal voltage limits given in Table 2a.
Where the light source is operated at a frequency exceeding 100 Hz, the unit shall comply with
the radiated disturbance limits given in Tables 3a and 3b.
5.3.6 Independent starters and igniters
Independent starters and igniters for fluorescent and other discharge lamps are tested in a
circuit as described in 8.9. They shall comply with the terminal voltage limits given in Table 2a.

5.4 Self-ballasted lamps
For self-ballasted lamps, the ballasting and starting arrangements are encapsulated with the
lamp into one single unit. These lamps are fitted with Edison screw or bayonet caps and can be
inserted directly into an appropriate holder.
Self-ballasted lamps shall comply with the terminal voltage limits given in Table 2a.
Where the light source is operated at a frequency exceeding 100 Hz, the unit shall comply with
the radiated disturbance limits given in Tables 3a and 3b.
5.5 Outdoor lighting appliances
5.5.1 General
For the purpose of this standard, the term "outdoor lighting" is used for the general lighting of
public areas such as streets, walkways, cycle paths, motorways, tunnels, car parks, service
stations and outdoor sports and recreational areas, for security and floodlighting of buildings
and the like. Moreover, requirements described in this subclause (5.5) apply to the (outdoor)
lighting appliances on private grounds, industrial estates and the like.
However, such lighting equipment may be subject to specific emission requirements which are
not covered by this standard, for example airport lighting.
This subclause (5.5) does not apply to neon and other advertising signs.
5.5.2 Mounting system
Generally, an outdoor lighting appliance is built up of a support and one or more luminaires.
The support could be:
– a pipe (bracket) or the like;
– a mast (column) arm;
– a post top;
– a span or suspension wires;
– a wall or ceiling.
Unless otherwise stated, the emission requirements described in this subclause (5.5) apply to
the luminaire (including the lamp) and no requirements apply to the luminaire support.
5.5.3 Integrated switching devices
Disturbances caused by the operation of integrated switching devices such as ripple control
receivers shall be disregarded.
5.5.4 Incandescent lamp luminaires
The condition of 5.2.2 applies.
